The invention relates to the technical field of mother and baby products, and discloses a baby stroller high in safety coefficient and capable of automatically stopping, the baby stroller comprises a mounting frame and rolling wheels, a rotating connecting shaft is fixedly connected to the outer side of the mounting frame, a movable groove is formed in the rotating connecting shaft, and a connecting spring is fixedly connected to the interior of the movable groove; and the outer side of the connecting spring is fixedly connected with a dielectric plate. According to the baby stroller , when the speed of the rolling wheels is too high, centrifugal force borne by the dielectric plate is too large, the dielectric plate continues to move outwards, the dielectric plate is inserted between a positive plate and a negative plate, after the working voltage of a piezoresistor 8 is reached, an external magnetic field is powered on, at the moment, a first magnetostrictive shaft is shortened, a limiting fulcrum shaft makes contact with an elastic limiting bag in the rotating process, electrorheological fluid is changed into a solid state from a liquid state through an external electric field, and therefore the limiting fulcrum shaft and the elastic limiting bag are connected into a whole, and the rolling wheels are stopped.
本发明涉及母婴用品技术领域,且公开了一种安全系数高的可自动止停的婴儿推车,包括安装车架和滚动轮,所述安装车架外侧固定连接有转动连接轴,转动连接轴内部开设有活动槽,活动槽内部固定连接有连接弹簧,连接弹簧外侧固定连接有电介质板。该安全系数高的可自动止停的婴儿推车,当滚动轮速度过快,导致电介质板受到的离心力过大,电介质板继续向外移动后,电介质板插入正极板和负极板之间,达到压敏电阻8的工作电压后,使得外加磁场通电,此时第一磁致伸缩轴缩短,限位支轴转动过程中与弹性限位囊接触,外加电场使得电流变液从液体变为固态,从而使得限位支轴与弹性限位囊连接为一整体,使得滚动轮止停。
